Fully Multi Coated Optics - All air-to-glass surfaces feature multiple layers of anti-reflective coating. Fully multi=coated optical systems deliver the brightest, highest-contrast images with the least amount of eye strain because only a very small percentage of light is lost before it reaches the viewer's eye.

Waterproof - Bushnell Marine Binoculars are O-ring sealed and nitrogen purged for total waterproof and fogproof protection. These models can withstand complete immersion in water and stay dry inside. The interior optical surfaces won't fog due to rapid temperature change or humidity.
